Winch Assembly
All components should be inspected for wear or damage
as they are removed. Refer to Figure 4-8, Visual Inspec-
tion. All seals that were removed should be replaced
during assembly. Carefully inspect all bearings that have
been removed. Used bearings often appear satisfactory,
but may fail when placed under a load. When in doubt,
it is recommended to install a new bearing. Any com-
ponent that indicates excessive wear or damage should
be replaced. The following reassembly and installation
sequence assumes a complete winch overhaul.

ITEM
INSPECTION REQUIREMENTS
CORRECTIVE ACTION
Brake Assembly
Check for cracked or broken belleville/coil
springs.
Replace springs if cracked or broken.
Inspect housing and covers for leakage or
damage.
Replace component if sealing surfaces or splines
are damaged.
Check the friction discs for wear, distor-
tion, or damage. The discs should be free
of hydraulic oil.
Replace the friction discs if the wear grooves
are worn away, the discs are burned, damaged,
warped, or exposed to oil. Brake cleaner may be
used to clean dust from the discs but will not re-
move impregnated oil.
Check the brake/motor shaft seals for leak-
age into the brake housing.
Replace damaged seals.
Inspect the brake/motor shaft for wear or
damage.
Replace a damaged shaft.
Check that the separator plates are fl at, free
of large blue areas (caused by overheating)
or damaged surfaces.
Replace damaged separator plates.
Inspect the piston for damage. Make sure
the seal groove and sealing surfaces are
in good condition.
Replace a damaged piston. Always replace the
piston seals when the brake is repaired.
P l a n e t a r y S p e e d
Reducer
Check the housing for leakage or damage. Repair or replace assembly.
Check output shaft bearing end play.
End play is 0.000-0.006”. End play is adjusted us-
ing the appropriate thickness retaining ring. See
parts manual.
Inspect sun gear and carrier assembly for
damage or wear. Sun gear should spin
freely in carrier assembly.
Replace assembly.
Winch Motor
Inspect motor shaft seal for wear or dam-
age.
Note: A leaky motor shaft seal will contaminate
the brake with oil and the brake will likely require
service. Replace seal.
Inspect vanes for wear or damage.
Normal wear results in slight fl attening of vane
tips, which does not impair motor performance.
Replace vanes if radius is reduced by 50%.
Inspect plates for wear or damage.
Normal wear results in marking of timing plates
which does not impair motor performance. Re-
placement of the timing plate is required if any
smearing, galling, or heat cracks are present.
